To a solution of (2-benzyloxy-3-methylphenyl)-(4-methoxyphenyl)-methanol (2.76 g, 8.25 mmol) in methanol (30 ml), a 20% palladium hydroxide catalyst (276 mg) was added and furthermore concentrated hydrochloric acid (0.27 mL) was added thereto. The mixture was stirred under a hydrogen atmosphere for 18 hours, and then the catalyst was filtered off. The solvent was distilled under reduced pressure, and the obtained residue was purified by silica gel column chromatography [developing solution=ethyl acetate:n-hexane (1:4)] to obtain the title compound (1.75 g, 93%).
